Product Use in the Workplace
- Council office - In some areas, council offices can often be hangout places for youths to pass the time. The prospect of a brick wall to write graffiti on can be tempting. What's left is a public building that looks abused.
- Shopping centre - Marble is a common substrate for both internal and external decorative structures in shopping centres. Being a place of high footfall, they are subject to much dirt and pollutants, and if external, are exposed to UV and weathering, which can result in damage and a poor aesthetic.
- Ornamental fountains - These decorative structures have been designed for beauty in mind. But this beauty only lasts if the on-going maintenance is kept up, protecting it from dirt, pollution and graffiti.

1 or 2 applications using low pressure spray. Alternatively a brush or roller may be used by applying to saturation point, taking care to avoid any sagging. One application is normally required, however, on porous substrates a second application may be required. Apply the second application in the same manner immediately after the first application, taking care not to allow the first application to dry out. Do not apply at temperatures below 5°C. Shake container well before use. Allow 72 hours to lapse before overcoating surfaces treated with Silane. On vertical surfaces, apply from the bottom up.
